Tom,

I have the Little Toni, I went with the OS 91FS non-pump. I used 60OZ torque servos on the ailerons, elevator and rudder. The plane turns nice and sharp. My tank blew out on the last flight and flooded the inside with fuel. I haven't replaced the tank yet. I recommend re-enforcing the 1/4 firewall. On my first Little Toni, the fiberglassed started breaking around the firewall. The plane flies really nice. I know some people have shoehorned way to much engine into it. The plane is light and flies fine within the recommend engine range. The plane was very easy to put together. Good luck and have fun.

Dave
